Abstract: 853,733. Centrifugal separators. WOLSTENHOLM, R. A. (Dorr-Oliver Inc.). Nov. 4 1956, No. 25185/56. Class 23 Apparatus for separating liquid material into heavy, light and intermediate fractions has provision for the recirculation of at least part of the heavy fraction and for regulating during separation the amount of intermediate fraction discharged. Liquid material is supplied to the separator rotor 101 (Fig. 1), through a feed pipe 121 after passing through a screen 132. Heavy fraction is discharged through nozzles 105 into a volute 106 which is connected by an external circuit to a return passage 109, water being introduced into the circuit if desired. The returned heavy fraction is impelled by vanes 113 through passages 114 to the part 116 of the separating chamber. The light fraction passes through the liner plates 151, through passages 142 and is discharged by a skimming device 141. The intermediate fraction from outside the liner plates passes through tubes 153 and passages 154, and is discharged by a skimming device 157, a valve 167 controlling the discharge. In the modification shown in Fig. 5, some of the heavy fradtion discharged from nozzles 234 into the volute 236 is returned with addition of water, if desired, to the rotor through valve controlled orifice 240. The intermediate fraction is discharged by the skimming device 273 into a chamber 275. Some of the intermediate fraction is discharged from the chamber 275 through a valve 279 and the rest is returned to the rotor through the annulus between sleeves 251 and 252 which also serves to feed the liquid material to the rotor. Cooling or heating fluid may be introduced into compartments 281, 282 of the casing 237. In the modification shown in Fig. 8 the walls 292, 293 of the volute 294 and the part 303 of the internal walls of the rotor are formed from synthetic rubber. The intermediate fraction is discharged by a skimming device 311, part of the discharging fraction being returned by passage 314 to the feed space 316. In a further modification (Fig. 9, not shown), some of the intermediate fraction is introduced into the return circuit for the heavy fraction. In the separation of a starch solution, starch solids, gluten, and fibrous solids constitute the heavy, light and intermediate fractions respectively.

Abstract: 1317823 Photo-eiectric position finding SOC PARISIENNE DES ANCIENS ETABS BARBIER BENARD & TURENNE 27 May 1970 [27 May 1969] 25518/70 Heading H4D A method of positioning an object comprises producing beams of light, converting said beams to light signals in a modulator, causing the beams or signals to be reflected from first reference marks on an object and to pass second fixed reference marks before they are detected by a sensor, the signals arriving at the sensor being indicative of the displacement of the object and being used to adjust its position. Three aluminium reference marks 2, 3, 4 on an object 1, Fig. 1, are illuminated by light from sources 18, 20 and a third source (not shown) and by means of lenses 5-7 and rhombohedral prisms 15-17 their images are projected on to three aluminium reference marks 11-13, Fig. 3. Disc 24 is rotated and the photo-cell 29-31 outputs are square-waves whose amplitudes are proportional to the positional error. The outputs of photo-cell 31, 30 are used for adjustment in two horizontal orthogonal directions (X, Y) and the difference between the outputs from photo-cells 31, 29 used for rotational correction (f 3 ) (Fig. 2, not shown), the sense of displacement being determined by phase comparison of the photo-cell outputs with a reference square wave. The second reference marks allow for errors in the positioning of the disc 24 axis and the object is thus positioned relative solely to the optical device 8, 9, 10 allowing extreme accuracy. In a modification, (Fig. 4, not shown), the positions of the light sources and the photo-cells are reversed.

Patent GB-692764-A (GB)
Title: A method and device for continuous refining of fatty oils, especially vegetable oils
IPC: C11B3/06
Filed: 1951-11-02
Abstract: <PICT:0692764/III/1> In the continuous refining of fatty oils to remove free fatty acids therefrom by quickly mixing a suitable proportion of lye therewith in a mixer and then immediately separating the soapstock formed in a centrifugal separator, the mixing is effected in a regulatable speed mixer, the speed of which is regulated, by watching the mixture through an inspection glass disposed in a pipe between the mixer and the separator, so that the mixing is kept below the emulsification limit between the oil and lye by increasing or reducing the speed.  So long as particles are visible through the inspection glass, an emulsion is not being formed.  The process enables strong mixing to be applied to oils built up from fatty acids of high molecular weight, such as rape seed oil which is built up mainly from erucic acid, where the emulsification risk is low, and a milder mixing to be applied to oils built up from fatty acids of low molecular weight, such as coconut oil which is built up mainly from lauric acid, where the emulsification risk is much greater.  In a suitable plant comprising a rotary mixer 3, consisting of a rotating disc 8 within a housing 4 for mixing and atomizing the oil and lye supplied through inlets 5 and 6 respectively, a short pipe connection 9 and a separator 10, a speed adjustment device 1 of any known type influencing the shaft 2 of the mixer is provided together with a device 12 having an inspection glass 11 in the pipe connection 9.  Purified oil is discharged from the separator through pipe 13 and soapstock through pipe 14.  Either the lye or the oil or both may be heated to 70 DEG C or more before being fed to the mixer.

Title: Improvements in or relating to disinfection of water by ozone or ozone-containing gaseous mixtures
IPC: C02F1/78
Filed: 1954-09-06
Abstract: 767,227. Disinfecting water. RHENO AKT.-GES. Sept. 6, 1954 [Sept. 7, 1953; Dec. 24, 1953], No. 25796/54. Class 46. Water is disinfected by directly introducing ozone or an ozone-containing gas into a conduit through which the water flows, simultaneously mixing the gas and water, and producing a turbulent current in the conduit before separation can take place, the turbulence being produced e.g. by baffles and occupying a path length sufficient to effect substantially complete disinfection of the water. The baffles may be replaced by blades, volutes, porous plates and the like. The conduit where the turbulent mixing of the two phases occurs may be constructed as a coil, a serpentine or a bundle of tubes. The pressure loss caused by the turbulence-producing means may be compensated by a mechanical pump connected to the discharge end of the conduit. Complete disinfection may be obtained in the apparatus after a length of path ranging from 5 to 10 metres. The first thorough mixing, and partial dissolution may take place in a mechanical pump at the inlet end of the system, the gas being introduced through an injector arranged at the inlet side of the pump or, alternatively, directly into the pump through a valve. Where no mechanical pump is necessary the gas is fed into the conduit by a water-jet pump. The surplus gas after disinfection is complete is removed by means of a pressure relief valve or by simple expansion. The amount of gas supplied may be adjusted in such a manner that substantially all the gas remains dissolved at the point where the water is delivered. Ozone generated in an ozonator 1, Fig. 2, is fed through a snuffling valve 3<SP>1</SP> into a pump 6, the internal pressure of which effects solution of some of the gas, and the gaseous and aqueous phases are thereafter maintained in turbulent contact by baffles 5, comprising e.g. crossed and slightly twisted metallic blades 7, Fig. 3, welded on a central wire 8, which baffles extend along a portion 4 of the conduit 2, Fig. 2, of length sufficient for complete disinfection to occur and comprising at least several metres.
